I had an LL message on the temp display and it will not stay above 35 degrees keeps going colder and colder

no rule of thumb
maybe if you got a different thermostat that has a lower setting than standard
however as upright freezers are very bad freezers compared to chest type freezers the lowest reading will be around the -35 degrees C
Why very bad -- every time you open the door you dump 20 degrees out onto the floor and the temp difference is more pronounced than opening the lid of a chest unit which keeps all of the cold in the unit
remember the colder the setting the more the compressor is working

More than likely, the thermostat on the unit is going bad. If the coils haven't been cleaned recently, then I suggest that you unplug the unit, clean it well and then cycle it back on. If it continues, then the thermostat that's located within the unit is going bad. Please refer to the owners manual for proper service and maintenance for your unit. https://www.appliancefactoryparts.com/content/pdfs/140265-1.pdf

If you have a frost free refrigerator then temp jumps as you discribe are somewhat normal during a defrost cycle. However it sound like your defrost temp may be getting too high. There is a limit thermostat on the freezer coils that keep the defrost temp from getting too high. The part is called a (defrost termination thermostat) and is a round disk about 1 to 1.5 inch in diameter clipped to the top of the freezer coils with 2 wires coming out of it. When cold, it allows power to the defrost heaters. At around 35/40 degrees it opens and shuts off power to the heater. 35/40 degrees sounds high for a freezer temp but that is behind the wall and only for a short time. Yours may be staying on too long or out of temp calibration needing replaced.

Hi,

How long does this temperature issue last? When you notice this issue how long does this sit at the hire temp, 1 hour? I am trying to understand why Heartland/Marvel would ask you to turn it off. Please let me know. Thanks

I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

It may be a faulty thermostat that is binding in colder weather.The thermostat opens and closs controlling the flow of the coolant.It almost completey keeps the coolant from circulating until reaching a pre determined temperature opening and closing to maintain that temp.It could be sticking wide open and colder temps thus moving the coolant too fast not allowing it tom remain in the engine block long enough to be heated.

it is cycling different because the environment is much colder..

Replace you Throttle positioning sensor (TPS for short)

I know the minimum operating temp for many refrigerators is around 33 F (about a degree above freezing or so). This is due to the refrigerant gas within the compressor and the fact that it is not stable at low temps. Typically, a refrigerator's minimum ambient temp should be 50 degrees F (10 degrees C).

I don't know if there is a whole lot you can do. The refrigerator really wasn't built to work in such cold weather. You may either have to relocate it, put a heat source near it or look into a special freezer that is *supposedly* able to operate in much colder ambient temps.

press bake and set to 550degrees. within 2 seconds press and hold the bake until 2 digits show on display, then release bake. the digits displayed is the amount of degrees the oven is off from original factory setting. If it reads 0, it is at original factory setting. you can now adjust by pressing the up button for a hotter oven, down for lower. it can only be done for 35 degrees. when done, hit clear/off. this will help to close the gap. if you are using an inexpensive thermometer, it can take a very long time for it to read the actual temp in the oven.

Hi, this problem is going to be with the running thermostat (cold Control). It has gone bad and stays open which in turn will keep the compressor running continually and will cause the fridge to get colder and freeze food. It can normally be located in the control panel inside the fridge (it is the control that has wires, the other is the damper). Locate the thermostat and replace it. If you have any other questions or concerns please feel free to comment again. Good Luck!! Mike
